DETAILED DESCRIPTION OF THE INVENTION

The present invention relates to a releasable locking apparatus. Preferred embodiments of the presently disclosed apparatus will now be described in detail with reference to the drawings in which like reference numerals designate identical or corresponding elements in each of the several views. In the description that follows, the term “top”, as is traditional, will refer to the end of the element which is closest to the operator, while the term “bottom” will refer to the end of the device which is furthest from the operator.

FIGS. 1-6 illustrate one preferred embodiment of the presently disclosed releasable locking apparatus shown generally as 10. The apparatus 10 has a male body 12 and a female body 14.

As shown in FIGS. 1 and 6, the male body 12 has a top section 16, a bottom section 18, and a male body rim 20 located at the bottom section 18. The male body 12 has a protrusion portion 22 located on the top section 16 of the male body 12. As shown in FIGS. 1, 3 and 6, the protrusion portion 22 has a middle section 24 with an upper portion 26 and a lower portion 28. As shown, the middle section 24 is generally round.

The protrusion portion 22 also includes at least one outer section 30 located on the upper portion 26 of the middle section 24. The outer section 30 has a radius with a length between the radius of the male body rim 20 and the radius of the middle section 24. There may be a single outer section 30, or there may be two outer sections 30 so that a bowtie shape is formed on the protrusion portion 22 as shown in FIG. 3. More than two protrusion portions 22 are also contemplated for this invention.

In addition, as shown in FIGS. 3 and 6, a wall section 32 is located on the middle section 24 at the protrusion portion 22 between the outer section 30 and the top section 26 of the male body 12. The wall section 32 provides a stop when the male body 12 and the female body 14 interlock.

Shown in FIGS. 1, 2, 4 and 6 is the female body 14 having a side wall 34 enclosing a void 36. The female body 14 also includes a bottom section 38 and a top section 40. The top section 40 includes a female body rim 42, at least one gap portion 44 complementary to the protrusion portion 22 of the male body 12, and at least one contact portion 46 extending from the female body rim 42 to the gap portion 44. The female body 14 also includes a spring 48. The spring 48 is located within the void 36 is oriented vertically as shown. As shown, the diameter of the spring 48 may be approximately the diameter of the void 36 to prevent the spring 48 from being moved from proper orientation. Other means for prevent the spring 48 from being moved are also contemplated, such as different geometries of the spring 48 and the void 36. Also, although a coil spring is shown, other springs such as leaf springs are also contemplated.

In addition, the female body 14 includes a contact element 50 as shown in FIGS. 1 and 5. The contact element 50 is movable within the void 36. It is located in the void 36 between the spring 48 and the contact portion 46 of the female body 14. As shown, the contact element 50 may be a plate shaped.

Also, additional means for keeping the spring 48 in proper orientation are contemplated using centering members for the elements which contact the spring 48. The contact element 50 may include a spring centering member in the middle of the plate on the side where the contact element 50 contacts the spring 48. In addition, the bottom section 38 of the female body 14 may include a bottom centering member at the center of the bottom section 38, wherein the bottom centering member is located within the spring 48.

As shown, in FIGS. 1 and 2, the diameter of the spring 48 is approximately the diameter of the void 36. However, the diameter of the spring 48 may be less than the diameter of the void 36. For example the diameter of the spring 48 may be approximately 80% of the diameter of the void 36 and still be restricted sufficiently so that the spring 48 keeps its alignment.

In addition, the spring 48 and the contact element 50 may be connected. Also, the spring 48 and the bottom section 38 of the female body 14 may be connected. Furthermore, the contact element 50 may be connected to the spring 48 and the spring 48 may be connected to the bottom section 38 of the female body 14.

In one embodiment, as shown in FIG. 1, the male body 12 includes an overhang 52 located at the male body rim 20. The overhang 52 creates a hollow 54 located between the overhang 52 and the protrusion portion 22.

The female body 14 includes a crown 56 on the contact portion 46. The crown 56 is a part of the contact portion 46 which extends past the top section of the female body 14, as shown in FIG. 6. The shape of the crown 56 is complementary to the shape of the hollow 54. As shown in FIGS. 1 and 6, the crown 56 is generally arc shaped. Other shapes are also contemplated for the crown 56.

The overhang 52 includes an overhang contact surface 58, and the rim 42 of the female body 14 includes a rim contact surface 60. The overhang contact surface 58 and the rim contact surface 60 are complementary so that the male body 14 and the female body 14 fit closely when in locking orientation.

Another embodiment of the apparatus 10 is illustrated in FIGS. 7 through 12. In this embodiment, the male body 12 includes a flange 62 located near the bottom section 18 of the male body 12. The female body 14 has a contact wall 64 located at the female body rim 42. As shown, the contact wall 64 extends past the contact portion 46 of the female body 14.

The shape of the flange 62 is complementary to the shape of the contact wall 64. As illustrated in FIGS. 7 and 8, the flange 58 and the contact wall 60 meet horizontally and with a 90 degree angle when the apparatus 10 is in a locked orientation. However, other angles and geometries are also contemplated.

In another embodiment of the apparatus, as described in FIGS. 1 through 6, and as shown in FIGS. 13 and 14, the bottom section 18 of the male body 12 further comprises an end cap 66. The end cap 66 may include inner walls 68 which are complementary in shape to the female side wall 34. The inner walls 68 may be longer than the length of the female body 14, and may be shaped so that the female body 14 is covered.

In addition, the bottom section 38 of the female body 14 may include a female housing 70. The housing may include a female chain 72 or bangle or similar structure.

In another embodiment of the apparatus, as described in FIGS. 7 through 12, and as shown in FIG. 15, the bottom section 18 of the male body 12 includes a male housing 74. The male housing 74 may contain the end of a chain 76 or bangle, or a similar structure. The female body 14 may include a clasp 78 or similar structure.
